Nodemon Server won't restart

The Nodemon is not restarting every time if there is any changes in the file, I need to stop the server with Ctrl-C and start the server again. I'm on Windows 64bit, I have changed in line 30, yet the server is not restarting. Why is it not restarting?

const express = require('express');
const bodyparser =require('body-parser')

const app = express();
app.use(bodyparser.json());


const database = {
    users:[
        {
            id:'123',
            name:'john',
            email:'john@gmail.com',
            password:'cookies',
            entries:0,
            joined: new Date()
        },
        {
            id:'124',
            name:'sally',
            email:'sally@gmail.com',
            password:'bananas',
            entries:0,
            joined: new Date()
        }
    ]
}

app.get('/',(req,res)=>{
    res.json(database.users);
})


app.post('/signin',(req,res)=>{
    if(req.body.email === database.users[0].email && req.body.password === database.users[0].password){
        res.json('success');
    }
    else{
        res.status(400).json('error logging in');
    }

})


app.post('/register',(req,res)=>{
    const {name , email , password} = req.body;
    database.users.push({
            id:'125',
            name:name,
            email:email,
            password:password,
            entries:0,
            joined: new Date()

    })
    res.json(database.users[database.users.length-1])
})


app.listen(3000,()=>{
    console.log("listening to port 3000");
})

this is my package.json

{
  "name": "Backend-brain-api",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon server.js"
  },
  "dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1",
    "ts-node": "^8.8.1"
  },
  "devDependencies": {
    "nodemon": "^2.0.2"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

If I define a start script inside package.json it gives me a whole new error:
